DeviceGuru writes: Jolla announced that its Sailfish OS is now fully compatible with Android, letting the Linux-based mobile OS run Android apps, as well as operate on hardware configured for Android. This makes the MeeGo-based Sailfish OS the first alternative mobile Linux OS to achieve the feat. Jolla also announced that a second batch of pre-orders for its Sailfish-based Jolla phones will open later this week, after having sold out its first batch in August.
